Neuroscience: Deep breathing changes your brain

Neuroscience: Deep breathing changes your brain

Humans have some intentional control over our brains (and minds and bodies) and focused breathing is one of those control mechanisms. “This recent study finally answers these questions by showing that volitionally controlling our respirational, even merely focusing on one’s breathing, yield additional access and synchrony between brain areas. This understanding may lead to greater control, focus, calmness, and emotional control.”

Vibration: A new theory of consciousness

Vibration: A new theory of consciousness

Article in Scientific American. One point. The article sees energetic fields underlying matter as if they are separate things, one the cause of the other. Whereas a naturalistic, postmetaphysical view might be that they mutually entail and co-generate each other within an ecological frame. The cause/effect frame still clings to a form of dualism.

Musk: merging of humans and technology essential to survival

[et_pb_section bb_built=”1″][et_pb_row][et_pb_column type=”4_4″][et_pb_text _builder_version=”3.17.6″] From Axios interview with Elon Musk: Musk said his neuroscience company, Neuralink, has about 85 of “the highest per capita intelligence” group of engineers he has ever assembled — with the mission of building a hard drive for your brain. “The long-term aspiration with Neuralink would be to achieve a symbiosis with artificial intelligence.” Wait. What? “To achieve a sort of democratization of intelligence, such that it is not monopolistically held in a purely digital form by governments…

Book discussion event on embodied cognition

Book discussion event on embodied cognition

Our discussions all, to some extent, relate to cognition. An important area of inquiry concerns whether some form of physical embodiment is required for a brain to support cognition in general and the self-aware sort of cognition we humans possess. THE BOOK Philosophy In The Flesh: The Embodied Mind And Its Challenge To Western Thought, by George Lakoff and Mark Johnson. Please note, while the title includes “Philosophy,” we are not a philosophy group and the book and discussion will…

Gaps in our focused attention

Gaps in our focused attention

Two papers released in the journal Neuron discuss these gaps, which happen 4 times every second. Hence the object of our focus only gets these quick snapshots and we have to piece them together to create the appearance of continual attention. The reason our focused attention is diverted so frequently is due to evolutionary selection pressures to remain vigilant to dangers in the environment around us. Thus any environmental distraction will interrupt our focus with this frequency. This reminds me…

The Singularity is Near: When Humans Transcend Biology

The Singularity is Near: When Humans Transcend Biology

Kurzweil builds and supports a persuasive vision of the emergence of a human-level engineered intelligence in the early-to-mid twenty-first century. In his own words, With the reverse engineering of the human brain we will be able to apply the parallel, self-organizing, chaotic algorithms of  human intelligence to enormously powerful computational substrates. This intelligence will then be in a position to improve its own design, both hardware and software,  in a rapidly accelerating iterative process. In Kurzweil’s view, we must and…

Affective neuroscience of self-generated thought

Affective neuroscience of self-generated thought

By Fox et al. (2018), Annals of the New York Academy of Sciences, 12 May, pp. 1 – 27. The abstract: “Despite increasing scientific interest in self-generated thought—mental content largely independent of the immediate environment—there has yet to be any comprehensive synthesis of the subjective experience and neural correlates of affect in these forms of thinking. Here, we aim to develop an integrated affective neuroscience encompassing many forms of self-generated thought—normal and pathological, moderate and excessive, in waking and in…

Consciousness and the brain

Consciousness and the brain

Book title by Stanislas Dehaene (New York: Viking 2014), a copy of which can be downloaded here. (Note it is in EPUB format. EPUB readers can be downloaded free on the internet.) From the Introduction, the section “Cracking consciousness”: “The word consciousness, as we use it in everyday speech, is loaded with fuzzy meanings, covering a broad range of complex phenomena. Our first task, then, will be to bring order to this confused state of affairs. We will have to…

Algorithm brings whole-brain simulation within reach

Algorithm brings whole-brain simulation within reach

An improvement to the Neural Simulation Tool (NEST) algorithm, the primary tool of the Human Brain Project, expanded the scope of brain neural data management (for simulations) from the current 1% of discrete neurons (about the number in the cerebellum) to 10%. The NEST algorithm can scale to store 100% of BCI-derived or simulated neural data within near-term reach as supercomputing capacity increases. The algorithm achieves its massive efficiency boost by eliminating the need to explicitly store as much data…

Recording data from one million neurons in real time

Recording data from one million neurons in real time

Given the human brain’s approximately 80 billion neurons, it would take tens of thousands of these devices to record a substantial volume of neuron-level activities. Still, this is a remarkable achievement. The system would simultaneously acquire data from more than 1 million neurons in real time. It would convert the spike data (using bit encoding) and send it via an effective communication format for processing and storage on conventional computer systems. It would also provide feedback to a subject in…
